I used Botallack: Chimney as an example before, so here it is again:
- Uncorrected photograph
- Auto-white balanced photograph
- Manually corrected photograph. I can't tell you exactly how much I changed each parameter (it would vary for each image, anyhow), but I did do the following:
Here's the full image:
- made it lighter
- added a bit of yellow
- increased the contrast
- increased the brightness
I manually corrected a few other images, too (I mostly just made them a bit lighter and added yellow; I didn't change the contrast or brightness on anything except Botallack: Chimney). I haven't changed the original posts, but here they are, side-by-side with their previous versions:
Darwin's Houses. Top: original photograph. Bottom: manual correction
Iron Age Round Houses at Butser. Top: auto-white balance. Bottom: manual correction.
I may do some more fiddling with the worst offenders that are already published, at another time.
